A duality relationship between fuzzy metrics and metrics [PDF]

open access: yes
[eng] Based on the duality relationship between indistinguishability operators and (pseudo-)metrics, we address the problem of establishing whether there is a relationship between the last ones and fuzzy (pseudo-)metrics. We give a positive answer to the

Convex combinations of nilpotent triangular norms

open access: yes, 2009
In this paper we deal with the open problem of convex combinations of continuous triangular norms stated by Alsina, Frank, and Schweizer [C. Alsina, M.J. Frank, B. Schweizer, Problems on associative functions, Aequationes Math.

T-generable indistinguishability operators and their use for feature selection and classification

open access: yes, 2019
T-generable indistinguishability operators are operators E that can be expressed in the form , where T is a t-norm and is the fuzzy relation generated by the fuzzy subset μ.

Power of Continuous Triangular Norms with Application to Intuitionistic Fuzzy Information Aggregation

open access: yes
The power operation of continuous Archimedean triangular norms (t-norms) is fundamental for generalizing the multiplication and power operations of intuitionistic fuzzy sets (IFSs) within the framework of continuous Archimedean t-norms.

On the representation of intuitionistic fuzzy t-norms and t-conorms

open access: yes, 2004
Intuitionistic fuzzy sets form an extension of fuzzy sets: while fuzzy sets give a degree to which an element belongs to a set, intuitionistic fuzzy sets give both a membership degree and a nonmembership degree.

On the representation of intuitionistic fuzzy t-norms and t-conorms

open access: yes, 2002
In fuzzy set theory, triangular norms and conorms are used to model conjunction and disjunction, respectively. An important class of triangular norms and conorms is the class of continuous Archimedean nilpotent triangular norms and conorms. It has been
